Definitions

• dimethylalkylamines for example in the form of salts of long-chain monocarboxylic acids, can be used for application in oily, solvent-containing wood preservatives (EP 147 976).
• dimethylalkylamine, tridemorph, fenpropimorph, a water-insoluble acid and a water-soluble acid can be used as water-soluble concentrates in wood preservation (DE-A-3 736 298).
• the novel wood preservatives are water-miscible and, on dilution of the concentrates with water, form clear to slightly opaque solutions.
• the aqueous solutions (impregnating solutions) obtained after dilution of the concentrates with water have a pH of from 4 to 8, preferably from 5 to 7.
• the aqueous impregnating solutions obtained are distinguished by the fact that the active components penetrate very effectively into the wood to be impregnated and thus result in effective wood preservation.
• a dimethylalkylamine is an N,N-dimethyl-N-alkylamine whose alkyl radical contains, for example, 6 to 20 carbon atoms. Dimethylalkylamines having 12 or 14 carbon atoms in the alkyl radical are preferred. In addition to the pure dimethylalkylamines, mixtures, for example mixtures of dimethyl-C 12 -alkylamine and dimethyl-C 14 -alkylamine (dimethyl-(C 12 /C 14 -alkylamine), may also be used.
• the novel wood preservatives contain C 8 -C 20 -dicarboxylic acid, preferably C 8 -C 14 -dicarboxylic acids.

• Other water-insoluble monocarboxylic acids eg. sorbic acid, benzoic acid, or cyclohexanecarboxylic acid, may also be used.
• 2-Ethylhexanoic acid is particularly advantageously used.

• dimethylalkylamine in particular dimethyl-(C 12 /C 14 ) alkylamine

• organic solvents are water-soluble or water-miscible polar solvents, for example glycols (ethylene glycol, propylene glycol), glycol ethers (ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, glycol ether acetates (butylglycol acetate), N-alkylpyrrolidones (N-methylpyrrolidone), alcohols, dimethylformamide, acethylformamide and dimethyl sulfoxide.
